Milling machine refers to the machine tool that mainly uses milling cutter to process various surfaces on the workpiece. Generally, the rotation motion of the milling cutter is the main motion, and the movement of the workpiece (and) milling cutter is the feed motion. It can process planes, grooves, and various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to mill the workpiece. In addition to milling plane, groove, gear tooth, thread and spline shaft, milling machine can also process more complex profile, with higher efficiency than planer, and is widely used in mechanical manufacturing and repair departments. In the 19th century, the British invented boring machines and planers for the needs of the industrial revolution such as the steam engine, while the Americans concentrated on the invention of milling machines in order to produce a large number of weapons. The milling machine is a machine with milling cutters of different shapes. It can cut workpiece of special shapes, such as spiral groove, gear shape, etc. As early as 1664, the British scientist Hooker made a machine for cutting by rotating circular cutters. This is a primitive milling machine, but the society did not respond enthusiastically to it at that time. In the 1840s, Pratt designed the so-called Lincoln milling machine. Of course, it is Whitney, the American, who really establishes the position of milling machines in machine manufacturing. The first ordinary milling machine (Whitney, 1818). In 1818, Whitney produced the world's first ordinary milling machine. However, the patent of the milling machine was obtained by Bodmer (the inventor of the planer with a cutter feeding device) in 1839. Because of the high cost of the milling machine, there were not many customers at that time. The first universal milling machine (Brown, 1862). After a period of silence, the milling machine became active again in the United States. In contrast, Whitney and Pratt can only say that they have done groundbreaking work for the invention and application of milling machines. The achievements of the real invention of milling machines that can be applied to various operations in the factory should belong to the American engineer Joseph Brown. In 1862, Brown of the United States produced the world's earliest universal milling machine. This kind of milling machine is an epoch-making innovation in the preparation of universal indexing plate and integrated milling cutter. The worktable of the universal milling machine can rotate a certain angle in the horizontal direction, and is equipped with end milling head and other accessories. When his "universal milling machine" was exhibited at the Paris Exposition in 1867, it achieved great success. At the same time, Brown also designed a form milling cutter that will not deform after grinding, and then manufactured a grinder for milling cutter, making the milling machine reach this level.
